hey there Robert, good to see ya again man! The easy answer is the age. In 1979 they dropped the internal balancing in order to cut costs. Since it was a low RPM Torque engine (not a performance engine) it was easy to do with a goofy looking counter weight hanging off the crank snout spacer and tack welded weights on the flex plate (and drilled flywheel). The BAD thing is..... Ford never offered the internal balanced 460 with a standard transmission, they where all automatic. So if you want to run a manual transmission in them you have to take a newer flywheel 7 clutch to your machine shop and have it "zero balanced" to make it work. Turns a simple clutch job into a couple grand in parts & labor. ((an Easter Egg for you though..... I have one of those custom clutch packs that I've had for years, because when it came time for the customer to pay the bill on that job, he ran out of money and I got stuck with it. Thats why I'm looking for a Top-Loader Ford 4speed transmission, because I've been waiting for years to do something with that ultra expensive flywheel & HD racing clutch that we had to pay for years ago))

@@BareRoseGarage Thanks Barerose! I am running a 73 C9VE-A block with a built C-6 behind it. Originally a 390 car with a 4 speed. Want to do a 351W 408 stroker swap this late fall. thanks for your reply and info you gave me. Cheers and blessings !

@@BareRoseGarage Whoa wait! Hold on BR, hold on there... 😁 First things first- The 79 block went to external balance to make the overall dia of the crank 'smaller' so as to have room for the extended cylinder jugs. The cyls are in fact quite a bit longer making them great candidates for super big-inch stroker kits. Ford did this to allow use of a longer deeper skirted piston for their HD truck applications. Second Thing- You are partially right about not having a 4 speed in front of a 460... until 1983 which then it was a hyd slave cyl style. BUT..... The 429 did have a toploader behind it, which is basically the same as a 460... by balance. Also the 351M/400 which shares the same bell housing pattern can be utilized on the early 460 and either a 351M/400 or 390FE flywheel can be used in it's place.... Might be just the FE flywheel as the 351M/400 flywheel has engagement issues? Can't remember for certain. Then you use the 390FE 11.5" clutch and pressure plate Top it off with an early 302 Pilot bushing. L&L Products sells these as custom parts as individual or as a kit. Not cheap! They use to have a lot of this info as it was a popular swap to run the NP435 and whatnot behind the 460s in mud trucks.

@@OlysGarage You caught that Egg there Oly..... lolololol I remember talking to you about that clutch set up a long while back, and can't remember right off hand what it was about the 429 flywheel that didn't work with the 460 out of the box. I think it's the center hole, I think it's smaller than the 460... but I could be wrong. Something about it make it not bolt right on. As for the reason behind it though..... I already have that clutch & flywheel from that botched job me and dad did for a guy years ago & it was for a Mud/Tough Truck project that fell through. Dad ended up with the 460 and I ended up with the Clutch, Bell & Flywheel. As for the external balanced (HD Truck) 460..... actually they aren't that bad of a foundation to build off of for stump pulling tow rigs (if you want to stay gas powered). If I do find a good set of DOVE, C8, or C9's out there, I'll probably re-use these D3's on that External Block I have out back for the Fairlane. They are better than the ones on that 1987 Block I have and will pep it up just enough to make it a little more fun. Would love to Stroke & Cam it as well... to get even more on the lower RPM side of things for it.

@@BareRoseGarage Setting me up again...ayyyeee... LOL I just remember that you need to use a pilot bushing from an early 302. So something must be different. I've got a 429 crank around here somewhere... if your curiosity is killing you. I can measure it. What I do know is for some reason when you bolt on the 351M/400 bell, it's not happy with using a 429 flywheel. Something with poor starter alignment with the ring gear. I think the 351M/400 bell was shorter....? than say a factory 429 bell. I've got a cast iron bell for the 335/385 series around here somewhere too. (Think organization needs to be instituted...lol) As for the heads, All i did to my D3s was put CJ valves in it and open up the exhaust sides a little bit. I had the head flowed on a flow bench AFTER doing the work.... dummy. Should have done a baseline first.... whoops. What year is the block the tunnel ram is sitting on?

Thanks Jim

Thanks man

Thanks a bunch!

Thanks for stopping by man!

Mmm hmmm

Oh Yeah See what you started 😜

@@BareRoseGarage 🤣🤣🤣🤣

I know!! Lolol I think they are taller than the roof line lololol

@@BareRoseGarage Exactly, let me know if you don't want them.

Id trade both of those K&N's for a Bug Catcher if ya got one... Lololol

No doubt!

Mine too, everyone goes the other way, but mileage always gets forgotten

Thanks ✌️

Mmmmm hmmmm

Thanks Nathan

👍

Thanks! You too!

Oh yeah 👍👍👍

Yeah it's going to be TOUGH to get this all together.

rolling in the floor lmao this made my day big mike

I just might have to take you up on that....... but I'll have to take out the front seat and leave the back on in there.... lolololol Thanks a mill Brother Hoop!

I know right..... Lolololol

☝️

That would definitely be cool as all get out but they are sure proud of those little things. But if I had my pick on that I'd look for the manual OD tranny out of an MGB and go with the 3 cylinder Perkins from a Massey Ferguson (same bellhousung pattern). Much more dependable and even more mileage... Lolol That little Dart doesn't sound that bad for the price either.

Thanks man 👍

Strange.. I thought I replied to this one. Weird... The block is a D1VE out of that 77 motorhome so she's right in the middle. I've toyed with the idea of taking that 460 out of the 87 F350 out to 521ci but doing it for torque not so much on the power side of things. But more than likely it will just be a run it as it is since it was just rebuilt a few months before the truck caught fire and he sold me the truck for a song.

@@BareRoseGarage thats a good block. Think its only ever so slightly taller deck than the earlier blocks. Not at all like the later ones.

They do make a sticker kit for it and the 302 that moves it to internal, but honestly if it's a race car that only sees the peek of it's Rpm once a week for an 8th of a mile at a time.... You are probably Right as Rain either way. It only becomes an issue over time and constant, like a Street Warrior that only sees the track a few times a year.

For sure... Lololol
